Sat, Feb 28, 2009from University of Alberta, via ScienceDaily: Solar Energy Performance With Plastic Solar Cells Improved With New MethodThe University of Alberta and the National Research Council's National Institute (NINT) for Nanotechnology have engineered an approach that is leading to improved performance of plastic solar cells (hybrid organic solar cells). The development of inexpensive, mass-produced plastic solar panels is a goal of intense interest for many of the world's scientists and engineers because of the high cost and shortage of the ultra-high purity silicon and other materials normally required.... "[A metaphor might be] a clubhouse sandwich, with many different layers. One layer absorbs the light, another helps to generate the electricity, and others help to draw the electricity out of the device. Normally, the layers don't stick well, and so the electricity ends up stuck and never gets out, leading to inefficient devices. We are working on the mayonnaise, the mustard, the butter and other 'special sauces' that bring the sandwich together, and make each of the layers work together. That makes a better sandwich, and makes a better solar cell, in our case".... After two years of research, these U of A and NINT scientists have, by only working on one part of the sandwich, seen improvements of about 30 per cent in the efficiency of the working model.... The team estimates it will be five to seven years before plastic solar panels will be mass produced but Buriak adds that when it happens solar energy will be available to everyone. She says the next generation of solar technology belongs to plastic.
"Plastic solar cell material will be made cheaply and quickly and in massive quantities by ink jet-like printers." ...

For some reason this story is making me hungry for mass-produced plastic.

Thu, Feb 26, 2009from Edinburgh Scotsman: RIP -- rest in (freeze-dried) piecesBODIES could be freeze-dried and shattered into dust to save space and help the environment, under plans being considered by a Scottish local authority.
East Lothian Council thinks the technique, invented in Sweden, could help ease cemetery congestion, while cutting emissions from cremations.
The process would involve freezing the dead body to -18C before submerging it in liquid nitrogen.
This would make the body so brittle it would disintegrate into dust when a vibration was passed through it... The process, known as promession, is considered more environmentally friendly than cremation, largely because it avoids the mercury pollution created by burning fillings in teeth and other metal objects in the body, such as replacement joints or surgical implants. ...

Wed, Feb 25, 2009from BusinessGreen: First Solar reaches 'dollar per watt milestone'The company said that during the fourth quarter of last year, the manufacturing cost for its solar modules stood at 98 cents per watt, taking it below the $1 per watt mark for the first time.... First Solar said it was confident that plans to more than double its production capacity through 2009 to more than one gigawatt would allow it to reduce costs further to a point where energy from solar panels can undercut that from natural gas and coal.
According to the company, it has already reduced costs from more than $3 a watt in 2004 to less than $1 a watt now and there is every indication that the trend will continue as production capacity increases. ...

Tue, Feb 24, 2009from McGill University, via EurekAlert: Peptides-on-demand: McGill researcher's radical new green chemistry makes the impossible possibleFast and simple 'enabling technology' being offered to the world on open basis... McGill University chemistry professor Chao-Jun (C.J.) Li is known as one of the world leading pioneers in green chemistry, an entirely new approach to the science which eschews the use of toxic, petrochemical-based solvents in favour of basic substances like water and new ways of making molecules.
The environmental benefits of the green approach are obvious and significant, but following the road less travelled is also paying off in purely scientific terms. With these alternative methods, Li and his colleagues have discovered an entirely new way of synthesizing peptides using simple reagents, a process that would be impossible in classical chemistry.... "This is really an enabling new technology," he added, "and since McGill has decided not to patent it, we're making our method available to everyone. We are paying the journal's open access fee, so anyone in the world can access the paper." ...

A new kind of science... making the impossible possible... available to everyone... where's the money in that?
